Almost unbelievable is technology that will allow us to flip through the channels with a simple twist of the hand. Want to raise the volume...just an upward pat. Or a photo on the screen can be enlarged by holding our hand out and spreading apart. Where have you seen this? The 2002 film Minority Report had Tom Cruise moving images around effortlessly on futuristic computer screens with just a few sweeping gestures. This year companies like Microsoft, Hitachi and others will begin selling devices that will make us think we are the Jetsons!
Microsoft has a new video game system called Project Natal that will use nothing more than the human body to play the games. They hope to one-up Nintendo's WII with this technology. In the months ahead Hitachi will offer TV's that will let people turn them on, adjust the volume and change the channels with simple hand motions. Laptops and other computers will follow. The companies behind this technology are GestureTek, Canesta and PrimeSense.
